This is a really great art! I love the colours you used, and the background is fabulous! If I were going to give a few tips it could be the following:Try making your lines a bit darker. Not thicker! Just darker, at least on the face. They blend in a little bit too much. Also I would suggest adding some darker shades to the face and eyes to make them pop out more.One other thing I would suggest would be adding a little colour to the cheeks and lips - just a hint of rosiness, to really make the character seem alive!

Cute OC you've got here! I'd like to get flowers from him. About the coloring... I think you could work the shading, it looks a little insufficient. I would recommend you this tutorial, it's very useful: [link]
